问题的大意就是将字符串中的字符按锯齿状(倒N形)垂直由上向下放置,最后水平从左向右读取.比如 ABCDEFGHIJKLMN,4表示 A G M B F H L N C E I K D J 按水平顺序读取的结果则为AGMBFHLNCEIKDJ.(原题目的描述就很有问题) 解决方案非常简单,可以发现字符串中第i个字符,其水平右边最近的元素为i+2*(row-1),其中row为规定的行高.而除了第一行和最后一行,中间的行的…
Given a nested list of integers, implement an iterator to flatten it. Each element is either an integer, or a list -- whose elements may also be integers or other lists. Example 1: Given the list [[1,1],2,[1,1]], By calling next repeatedly until hasN…
